UNITED STATES PATENT OF ICE.

OHAUNOEY O. PARKER, OF BROOKLYN, YORK.

IMPROVEMENT m EvEeLAssEs.

Specification forming part of Letters Patent No. 173,050, dated February1, 187 6 application filed January 25, 1876.

To all whom it may concern:

Be it known that I, GHAUNGEY O. PARKER, of Brooklyn, in the county ofKings and State of New York, have invented a new and valuableImprovement in Eyeglasses; and I do hereby declare that the following isafull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of my invention. Fig. 2 is adetached view of the fastenings, showing the two connected. Figs. 3 and4 are similar views, showing the fastening before being connectedtogether.

This invention has relation to eyeglasses, and its object is to providea means by which the lenses may be readily secured in the frame of theeyeglasses, whereby the necessity of employing screws, rivets, or pinsare entirely avoided; and the invention therefore consists in securingto the two ends of the frame, where they join, a tongue with shoulders,and a plate with side flanges or lips, the tongue passing down betweenthe flanges or lips, after which they are pressed inward, therebysecuring the tongue from lifting out, and the shoulders upon the tonguepre veutin g it from being withdrawn,

as will be hereinafter described.

In the accom pan yingdrawings, Ais designed to represent the frame ofthe eyeglass, having secured thereto the hinge-spring or nose-piece B,one of said frames having the usual handle O and catch at. These partsdo not differ materially from the eyeglasses of the ordinaryconstruction, and further description is deemed unnecessary to the fullunderstanding of my invention, which consists simply in connecting thetwo ends of the frame A together, which will be readily understood fromthe following description:

. Upon one end of the frame A is secured, by

The advantages of connecting the frames together, as above described,will readily be seen from the fact that such a fastening is muchstronger than screws, and can be more easily adjusted, and the eyeglassis greatly .reduced in the cost of its manufacture, as the making andadjusting the screws requires skilled labor, while my improvementrenders such labor entirely unnecessary, as the attachments can be cutor stamped out by dies and soldered on the eye-frames, when they areready to be secured to the glass.

When it is desired to disconnect the two ends of the frame, all that isnecessary is to press open the lips. The lips also form a catch to holdthe frames together when folded.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The method, herein described, of connecting together the framesofeyeglasses, consisting of the plate E, with flanges c, and the tongueD, with shoulders 12, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
